加载软件包时禁用消息 [英] Disable messages upon loading a package

问题描述

我在R(ROCR)中有一个需要在我的R环境中加载的软件包.装入包装后，将打印一组消息.通常，这很好，但是由于我的R脚本的输出正用于进一步分析，因此我想完全禁用所有这些输出.我怎么做?此外，我宁愿完全不必修改ROCR来执行此操作，这样该脚本的未来用户也不必这样做.

I have a package in R (ROCR) that I need to load in my R environment. Upon loading the package, a set of messages are printed. This is ordinarily fine, but since the output of my R script is being used for further analysis I want to completely disable all of this output. How do I do that? Furthermore, I'd prefer to do it without having to modify ROCR at all, so that future users of this script don't have to do that either.

到目前为止:

• sink()在这里不起作用-将stdout和std err都重定向到/dev/null对我没有任何作用.
• 不足为奇的是，options(warnings=-1)也不执行任何操作，因为这些警告本身并不是警告.

• sink() doesn't work here - redirecting both stdout and std err to /dev/null does nothing for me.
• Unsurprisingly, options(warnings=-1) does nothing either, since these are not warnings, per se, being printed.

有什么想法吗?

推荐答案

只需在library()调用周围使用suppressMessages():

edd@max:~$ R

R> suppressMessages(library(ROCR))
R>                                               # silently loaded
